Functional Range Release (FRR™)

Functional Range Release (FRR™) is an advanced system of soft-tissue treatment based in the principles of myofascial release, but with multiple improvements. The treatment system, in combination with the Functional Anatomic Palpation Systems® methods of palpation, focuses on the assessment, localization, and systematic treatment of soft-tissue lesions (adhesions) and areas of fibrosis (scar tissue) which develop as a result of injury, repetitive strain, and cumulative trauma.

  • What is PAILS?

    Utilizing the trademarked PAIL's Progressive Angular Isometric Loading®) and Tissue Tension Technique®, Functional Range Release® soft-tissue management system expands on the basic tenets of myofascial-release treatments by simultaneously assessing, expanding, and strengthening the patient’s functional range of motion.

    With regards to soft-tissue release, PAIL's®, similar to PIR (post-isometric 'relaxation') allows a temporary reduction in the stretch reflex threshold, thus immediately allowing an increased range of movement of a joint. PAIL's® application however also develops strength in this newly acquired range in order that the body will expand its functional range of motion.

PAIL's® application in injury rehabilitation utilizes techniques which produce strength and endurance in increasing ranges of movement, thus extending the functional range. When utilized with the Functional Range Release® system it allows practitioners to simultaneously release tissue tension while commencing the rehabilitative process, which will:

  • teach the CNS how to maximally recruit muscle fibers
  • decrease the onset of muscular inhibition and wasting that occurs post injury
  • improve neural drive to inhibited muscular tissue
  • expand the range of motion in which forces can be generated (ie. expand the functional range)
